That be 30-40 foot humpback whales in Kenai Fjords area- just out of Seward.
The big guys (gals?) are moving from right to left.
The vapor is mostly water that collects in the blowhole (nostril) well that is vaporized when whales breath out (the air
is exhaled at more than 100mph). There is also some vaporized air as the warm breath hits the cold outside air.
I was in a sightseeing boat that was paralleling the whales at the proper and legal distance. A long lens was used to bring them in.
No chumming with krill .

Having had one experience with these behemoths, I know how exciting it is just to be in their presence...don't know if you got to see them breech...guess not as you would have posted those...now that must be a thrill...we also didn't get to see that awesome behavior. Nice shots Charlie.

Thanks Eric, Sunny, Tom, Ken and (I guess ) Ron too.
I have a few more for this little run, including a couple of breaches- which Eric correctly calls "awesome." Well, it is if you think it's awesome for a 40-foot, 40-ton whale to jump almost all the way out of the water .

Thank you Sritri and Tim.
Sunny just sent me a PM of an incredible shot- and video- of a young humpback breaching COMPLETELY out of the water. Much harder to do when a whale weighs 40,000 pounds.
Out of consideration he didn't post it on my thread- which I think is pretty cool.
So I will post the link here. One good thing about being a member of the Peanut Gallery is that I can acknowledge really good stuff without feeling (too ) jealous .
So, here's the link:http://www.petapixel.com/2012/08/11/amazing-photo-of-a-humpback-whale-breaching-a-boat-length-away/
Oh, I have some whale breaches coming up in the next couple of days.
